Osteospermum plant named ‘Fidostwhispo’

ABSTRACT

A new and distinct cultivar of  Osteospermum  plant named ‘Fidostwhispo’, characterized by its compact and mounding plant habit; freely branching growth habit; freely and early flowering habit; large daisy-type inflorescences with white and violet bi-colored spoon-shaped ray florets; and good garden performance.

Botanical designation: Osteospermum ecklonis.

Cultivar denomination: ‘FIDOSTWHISPO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis, and hereinafter referred to by the name ‘Fidostwhispo’.

The new Osteospermum plant is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the program is to create and develop new compact Osteospermum plants that are freely branching and freely flowering and have attractive inflorescence coloration.

The new Osteospermum plant originated from a cross-pollination by the Inventor in May, 2006 of an unnamed proprietary selection of Osteospermum ecklonis, not patented, as the female, or seed, parent with Osteospermum ecklonis ‘Flower Power Spider Purple’, not patented, as the male, or pollen, parent. The new Osteospermum plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Lier, The Netherlands in October, 2006.

Asexual reproduction of the new Osteospermum plant by terminal cuttings in a controlled greenhouse environment in De Lier, The Netherlands since November, 2006, has shown that the unique features of this new Osteospermum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Osteospermum have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Fidostwhispo’. These characteristics in combination distinguish ‘Fidostwhispo’ as a new and distinct cultivar of Osteospermum:

-   -   1. Compact and mounding plant habit.     -   2. Freely branching growth habit.     -   3. Freely and early flowering habit.     -   4. Large daisy-type inflorescences with white and violet         bi-colored spoon-shaped ray florets.     -   5. Good garden performance.

Plants of the new Osteospermum differ from plants of the female parent selection primarily in plant and growth habit as plants of the new Osteospermum are more compact in plant habit and more uniform in growth habit than plants of the female parent selection.

Plants of the new Osteospermum differ from plants of the male parent, ‘Flower Power Spider Purple’ primarily in ray floret color as plants of ‘Flower Power Spider Purple’ have purple-colored ray florets.

Plants of the new Osteospermum can be compared to plants of the Osteospermum ‘Nasinga White’, not patented. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Osteospermum differ primarily from plants of ‘Nasinga White’ in ray floret color as plants of ‘Nasinga White’ have creamy white-colored ray florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Osteospermum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Osteospermum plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Fidostwhispo’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph, following observations and measurements describe plants grown during the spring and early summer in 10.5-cm containers in a glass-covered greenhouse in De Lier, The Netherlands and under conditions and practices which approximate those generally used in commercial Osteospermum production. During the production of the plants, day temperatures ranged from 17° C. to 35° C. and night temperatures ranged from 15° C. to 25° C. Plants were pinched one time. Plants were 13 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
